CHURN.

f3.'L-ECIFICATION forming part of Letters Patent No. 345,097, dated July 6, 1886.

Application filed April 26, 1886. Serial No. 200,166. (No model.)

To all whom it may concern:

Be it known that we, NATHANIEL S. AN- ;omzws andHIRAMF. BURNAP, citizens of the United States, residing at Dubnque, in the county of Dubuque and State of Iowa, have invented certain new and useful Improvements in Ohurns; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appcrtains to make and use the same.

Our invention relates particularly to that class of churns which are used in butter-factories for testing numerous samples of cream or milk simultaneously, and our object, mainly, is to produce a churn combining unusual simplicity, cheapness, and efficiency; to which ends the invention consists in the construction and arrangement of parts, all as more fully hereinafterdescribed and claimed.

For the better understanding of the details of construction and arrangement attention is invited to the accompanying drawings, in which Figurcl representsa plan view of the churn complete; Fig. 2, a vertical longitudinal section on the linear: or of Fig. 1, and Fig. 3a vertical transverse section on the line 7 y of said figure.

Like letters of reference denote corresponding parts.

A represents the snpporting-frame, which is preferably rcctangular,aml is entirely open,

except at its ends. 011 the inside of this frame, at opposite points upon the sides and near the center, are secured two guide-bars, a a, at the rear ends of which is secured arigid guideboard, B, extending across from side to side of the frame A, and provided with a series of perforations, Z), to receive the tubesX for holding the samples to be churned.

O is the transverse movable head, which is slotted at each end to fit the guide-bars a a, and,likc the guide-board B, is provided with a series of perforations, 0, except that they are made tapering to receive and hold the taperin g necks of the sample-tubes X. These tubes are arranged horizontally, as shown, and after the corks d are inserted they are tightened in the head 0 by anut, e, on the threaded end of a bolt, e, which passes through said head and through a follower-board, D, and screws into the crosshead E. This followerboard D is arranged transversely, so as to press against the corks d, and it will be seen that by turning the nut e in the proper direction both the head 0 and board D will be drawn together, the former tightening itself around the necks of the tubes and the latter forcing in the corks. The drivingqjiower consists of the pitman F, which is attached to the cross-head E and to a crank axle, F, having a fly-wheel, G, on one end, and a driving-pulley, G, on the other end, which connects by belting H with the large driving wheel H, mounted on the opposite end of the frame A. By turning the wheel H moven'ient is transmitted to the pitman F, which reciprocates the board D and head 0, together with the tubes, they being guided by the board B.

With a construction like that herein described we effect a saving of at least fifty per cent. of the cost to manufacture other churns of this class, while it is as efficientin all respects and as easy to handle.

What we claim, and desire to seen rc by Let ters Patent, isv 1. In a churn of the character described, the combination of the frame A, provided with the guide-bars a a, and the rigid perforated guide B, the perforated head G, the sample-tubes, means for securing said tubes in head 0, and means for operating the said head, substantially as described.

2. In a churn of the character described, the combination, with the frame A, provided with the guide-balsa a, of the rigid guideboard I3, the movable head C, provided with tapering perforations c, the tapering neck, sampk-tubes, means for securing said tubes in head 0, and means for operating said head, substantially as described.

3. In a churn of the character described, the combinationof the tapering neck, sampletubes, the movable head 0, provided with tapering perforations c, the follower-board D, and the cross-head E, provided with thescrewbolt 0, having a nut, e, on its outer end, substantially as and for the purpose set forth.

In testimony whereof we aflix oursi gnatu res in presence of two witnesses.
